Attached is a snapshot of our app. For the "Area" section we have almost 3000 items. If we used a spinner or picker it would be very user unfriendly to let him scroll through the whole list till he reaches his desired destination. This is why we think an AutoComplete control solves the answer. I was given this XAML solution

I'm still new to Xamarin and not a professional, so I was unable to implement and use it 
Any samples out there for beginners like me? or if someone would be so kind and suggest an alternative for this problem I would be grateful.
Any help is much appreciated! Thanks.
